Abstract

Une compensation de pixel négatif dans un dispositif tactile est divulguée. Le dispositif peut compenser un effet de pixel négatif dans des sorties de signal de contact dues à une mise à la masse médiocre d'un objet touchant le dispositif. Pour cela, le dispositif peut commuter vers une configuration pour mesurer la condition de la mise à la masse de l'objet en contact et utiliser en conséquence la mesure pour compenser les valeurs de sortie de contact provenant du dispositif. Dans la configuration commutée, un premier ensemble de lignes du dispositif peuvent être commutées entre un couplage à une entrée de signal de stimulation pour commander le dispositif, un couplage à une sortie de signal de condensateur pour émettre un signal indicatif de la condition de mise à la masse de l'objet, et un couplage à la masse. Un second ensemble de lignes du dispositif peuvent être couplées à une sortie de signal de contact pour émettre un signal indicatif du contact de l'objet au niveau du dispositif.
